|1||Headers form an important part of all types of boilers.|
|2||Steam from the generating tubes is collected in headers which are
therefore always under pressure.|
|3||This pressure may vary from 300 psi to 2000 psi. Since headers are
always under pressure, the utmost care is taken by us while
|4||Depending on the generating capacity of the boiler the header sizes
fabricated by us vary from 100 mm to 600 mm NB. The stubs of
various sizes are very carefully welded to the main body of the
header to provide the desired openings from the header.|
|1||The necking hinders of the Company are made by hot press and
retracting of seamless steel pipes at special hinder necking
|2||In this way, the hinders will have thicker walls and cleaner
surface. The necking cover will form membrane stress rather than
bending stress with desired stress performance under the effect of
1. Strength calculation report with applied materials information.
2. 100%NDT(non-destructive inspection) report of steel plate, tube
and welding rod.
3. 100%X-ray inspection report (welding seam): to ensure the
quality of the entire boiler.
4. Hydraulic test report: ensure the standard working pressure and
5.Excellent in welding quality, highly automatic, safe and reliable.
Enamelled Corrugated Sheet Baskets are a compact arrangement of
profiled metal sheets placed in the Air Preheater rotor in two or
more layers and plays the most important role in the process of
The bottom layer, or the cold end layer, is where the air enters
and the flue gases are discharged, and is therefore, subjected to
severe corrosion due to acid dew point. The Material of
Construction and the Profile design of the Heating Elements depends
on the operating conditions, quality and type of fuel, etc.
Steam distribution headers are fabricated out of carbon steel or
alloy steel seamless tubes. Customized or tailor made items are
offered. Headers, after fabrication, are stress relieved to make
the Steam distribution headers free from stresses. They are big
pipe headers that transfer water from the downcomers to the risers
through a combustion zone where the water gets partially heated to
steam from the heat of fuel combustion.
